Why this helps
Tracking which address needs a check across multiple threads adds mental overhead.
- Turn an existing reaction habit into a clear signal.
- Avoid copying addresses into a separate tool.
- Keep the check attached to the message that needs it.

Build it in a few focused steps.
- 1Connect Slack and Emailable to Notis once through the portal.
- 2Create a new automation in Automations.
- 3Write one prompt instructing Notis to verify an address from a message marked with your chosen reaction and report the result.
- 4Choose Message Reaction Added, set its emoji and optional channel filter, choose a run-report channel, and test with one message.
Questions about this workflow
Can I choose any reaction?
